Basketball spinner

ABSTRACT

The invention includes a concave cup specifically designed to hold various size basketballs. The cup has a stem which inserts and is held securely in a precision bearing, which in turn is held firmly in the splined finger gripping portion of the invention. The splined finger gripping portion of the device is held securely on the finger of a person, by an o-ring. The o-ring rolls up and down on the splined portion and is prevented from rolling off by the molded protrusions at the bottom of the splined finger gripping portion of the invention. The splines are tapered to allow for expansion and contraction to fit various finger sizes.

BACKGROUND OF THE INVENTION.

[0003] The present invention is a toy, it relates to a ball spinning apparatus for the amusement and training of the user in the skill of spinning a basketball on one finger. Before this invention most products were dangerous, because of sharp pointed parts to pierce a ball, or were not specifically intended to use a real basketball for the development of the basketball spinning skill.

BRIEF SUMMARY OF THE INVENTION.

[0004] The general idea of the Basketball Spinner, is an apparatus that is placed over one finger of either hand of the user. A basketball of any size is then placed in the ball-holding portion of the device. The ball is then lightly struck on its side causing it to begin rotating.

[0005] The combination of a firm holding device on the finger, a specially designed ball holding portion, and a precision bearing at the tip of the finger gripping device, enable anyone to spin a basketball on one finger, smoothly and for an indefinite amount of time, with the aid of the device.

DETAILED DESCRIPTION OF THE INVENTION.

[0016]FIG. 1 The ball spinning device includes a ball holding cup 1 designed specifically to hold any size basketball, NBA, WNBA, street, or pee-wee. The basketball fits perfectly in the cup 1. The stem 2 of the cup 1 is designed to be inserted into a precision bearing 3, and onec fully inserted the tab 4 at the bottom of the stem 2, holds the cup 1, tightly in place on the precision bearing 3. The ball holding cup I is made of plastic from an injection molding process. FIG. 2 shows a bottom view of the ball cup 1, with the stem 2, inserted into the precision bearing 3. The precision bearing will be supplied by a precision bearing manufacturer. FIG. 3 is a sectional drawing of the ball cup 1, stem 2, and tab 4. FIG. 4 is an enlarged view of the ball cup 1, stem 2, and tab 4. FIG. 5 Illustrates the splined finger gripping, bearing holding, portion 5 of the basketball spinning device side view, the protrusions 6, located at the bottom of the splined finger grippers 8, stop the o-ring 7, which is movable, it rolls up and down, and holds the splined finger gripping portion 8, tightly to the user's finger. The splined finger grippers 8, are each tapered 9, to allow for contraction and expansion to fit various size fingers. FIG. 6 is a sectional view of the finger gripping portion 5, showing the area where the finger is held 10, and the area where the precision bearing 3, is held., the protrusions 6, are also shown in this view. FIG. 7 shows the top view of the finger gripping device 5, and where the precision bearing 3 is held. FIG. 8 is an enlarged view of the finger gripping device 5, and the finger area 10, also the precision bearing 3, area. FIG. 9 shows a side view of the entire unit, ball holding cup 1, finger gripping portion 5, protrusions 6, to stop o-ring 7, from being moved down too far. Splines 8, are tapered 9. 

1. a device used to balance and spin a basketball on one finger, whose cup apparatus that holds the basketball, is contoured to receive and hold a basketball of any size. a bottom stem on said ball cup apparatus is pressed into a precision bearing. tabs on bottom stem hold said ball cup apparatus tightly in said precision bearing.
 2. ball holding cup apparatus of claim 1, with said precision bearing is pressed into the finger gripping apparatus of said invention. Finger gripping apparatus has a cavity that accepts and holds tightly said precision bearing, and said ball cup apparatus: Finger gripping apparatus has tapered splines to allow expansion and contraction of size of said finger gripping apparatus. o-ring can be moved up and down said tapered splines of said finger gripping apparatus to controll tightness on finger. protrusions on bottom of splines prevent o-ring from slipping off said finger gripping apparatus.
